EMIL HOLLMIG, OF CHICAGO, ILLINGIS, ASSIGNDB, BY IYTESNE ASSIGNMENIl, TO THE KLEIN MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE.

AUTOMATIC FUEL SAVER AND AUXILIARY AIR REGULATOR.

To all whom it may concern:

Be it known that I, EMIL HoLLMi'e, a citizen of the Republic of Germany, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented a new and useful Automatic Fuel Saver and Auxiliary Air Regulator, of which the following is a specification.

My invention pertains to a new and useful automatic fuel'saver and auxiliary air regulator, and the device is particularly adapted for use with an internal combustion engine. being connected with the intake manifold of the engine. 7

The main objectof the invention is to provide a fuel savingdevice in the form of an auxiliar air feeding and regulating device which acts entirely automatically and supplies additional air to the fuel mixture during the passage thereof from the carburetor through the intake manifold to the engine, and which device supplies suchadditional or auxiliary air in regulated quantities and in accordance with the actual requirements, supplying a larger amount of air with a rich fuel mixture and a slight amount or none whatever with a leaner fuel mixture.

Another object is to provide such a fuel saving device with means for adding the air in alfine spray into the fuel. mixture as it passes to the engine. 7

Another object is to provide such a device which is automatically actuated by the fuel itself during its passage from the carburetor to the intake manifold.

And another object is to provide the device with means for accurately regulating the same so that it will feed the exact amount of air suitable for the particular richness of the fuel mixture and for the particular construction and power of the engine.

Other objects and advantages are attained with my invention, one form of which is described in the present specification and illustrated in the accompanying drawings, in which;

F 1 is an elevational view illustrating my invention mounted in position between the carburetor and the intake manifold of the internal combustion engineof an auto mobile.

Application filed May 1, 1925. Serial No. 27,231.

Fi 2 is an elevational view of the device. Fig. 3 1s a vertical sectional view, taken on line 3-3 of Fig. 2.

Fig. at is a vertical sectional view through the valve stem, taken on line 4 -4; of Fig. 2. Fig. 5 is a horizontal sectional view of the device taken on line 5-5 of Fig. 3.

Fig. 6 is a horizontal sectional view through the inlet valve, taken on line 6 -6 of Fig. 4. V

Fig. 7 is a fragmentary plan view partly in section, taken on line 7-7 of Fig. 4, and Fig. 8 is a plan view .of my automatic fuel saver and auxiliary air regulator, particularly arranged in the present form for con veniently mounting it between the usual connected flanges provided on the conduit parts of the carburetor and the intake manifold of an automobile engine, as shown in Fig. 1. In the drawings I have illustrated one form of my invention and have shown it connected with the engine by inserting it between the carburetor 11 and the intake manifold 12 of the engine, the device being fastened to the conduit parts 13 and 14 connected respectively with said carburetor and intake manifold.

The particular form of my invention illustrated comprises a substantially cylindrical member or casing 15 which forms a fuel channel 18 for the passage of the fuel mix.- ture therethrough, from the carburetor 11 to the intake manifold 12; and this casing is providedwith cylindrical flanges 17-and 1.8 for attachn'ient to the corresponding flanges 13 and 14: of the conduit parts 13 andv 14.

The air delivering and feeding means preferably comprises a semi-aniuilar air feeding member 19 which is mounted in an enlarged annular seat at one end of channel 16, and is provided with perforations 20 which are directed so as to feed the air in a fine spray into the channel 16 and thus to thoroughly mingle with the fuel mixture passing through the channel. Alongit-udinal bore 21 in the casing communicates with the air feeding member 19 and with a transverse bore 22 which opens through the bottom of the easa.

The automatically eperating valve means t in or mechanism comprises a stem which rotatably mounted in a shoulder portion 2!- provided at one side of the casing 15, and has an intermediate portion 23 extending into the channel 16 of the casing. The lower end of this stem is cored out to provide an air receiving space or chamber 25 open at the. bottom, and a side opening 26 leads from said chamber and is registrablc with the longitudinal bore 21 for admitting air to the perforated feed member 19. A curved valve member or flap 2? is mounted on stem portion 23 with suitable fastening means, and normally extends across the channel 16 when the engine is at rest, said member being slightly smaller than the channel to permit passage of a small quantity of fuel through the channel before the valve mechanism is actuated for the admission of additional air.

Spring means 28 is provided for moving the valve mechanism to the clos d position, and for keeping the same closed when the engine is at rest. This spring means is prefe ably mounted on the upper end of the stem 23, engaging the casing with one end, and having its other end attached to a castellatcd disc or member 29 which is a-djustably mounted on the stem, as by means of a pin 30 placed in a pair of the several slots 31 provided between the castles 31 on said disc, or the disc may be made adjustable in any approved manner. This spring can thereby be adjusted or regulated to provide the required tension in order to permit the flap valve 27 to move with the fuel mixture passing through the device and thereby to operate the valve means 25, 26, etc., so as to exactly suit the particular richness of the fuel mixture and the particular size and power of the engine.

With a construction as above disclosed, it is apparent that the device will operate entirely automatically, and that when the engine is running fast and a large amount of fuel is passing through the device, from the carburetor to the intake manifold, that the suction of the engine will be greater, and consequently that the flap 27 will be actuated in accordance and opened to a greater extent, than when the engine is running slowly, and it.- is evident that the device will thus automatically feed a proper amount of anxiliary and additional air to the fuel mixture during its passage from the carburetor to the intalm manifold, and will feed said air in a line spray thus aiding in fully vaporizing the fuel and producing a proper and economical fuel mixture, thereby greatly clin'iinating the deposition of carbon.

Although I have illustrated and described my invention in a particular or preferred form, and have mounted it in a preferred position in the conduit between the carburotor and the intake manifold it should be understood that l contemplate various Inoili licalions and changes in the ('Hlifiil'll 'ihli and in the positioning of the invention. and dcsire to include such as properly come within the scope of the annexed claims.

Vv hat- I claim as my invention and desire to secure by Letters Patent is.
